DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0073] Figure 1The main reason why the existing photovoltaic module pressing blocks are prone to local damage during use, especially when subjected to wind pressure or snow load, or after long-term use, is that: Figure 1 In the related art, the pressing block for photovoltaic modules has a weak supporting effect on the second panel 12 from the side away from the first panel 11 in the direction in which the second panel 12 extends, resulting in the first panel 11 and the second panel 12 flipping outwards under wind pressure such as negative pressure or snow load, or after long-term use, thereby increasing the angle between the pressing block and the frame of the photovoltaic module, and further causing the second panel 12 to break or rupture. Moreover, when the deformation of the photovoltaic module is too large, the center position of the photovoltaic module is lower than the edge position of the photovoltaic module, and the pressing block flips outwards, causing the first panel 11 and the frame of the photovoltaic module to shift, that is, the frame will be misaligned or slip with the pressing block, causing the photovoltaic module to fall off the photovoltaic bracket.

The first direction L1 here is perpendicular to the second direction L2. The third direction in which the length of the second plate 12 extends, the first direction L1 and the second direction L2 are perpendicular to each other. The third direction in which the length of the second plate 12 extends is roughly perpendicular to the paper surface. The length of the second plate 12 is greater than or equal to the thickness of the second plate 12.

[0076] The second plate 12 includes: a first end and a second end that are oppositely distributed along a first direction L1 extending along the height of the second plate 12, such as Figure 1 The first end is the upper end of the second plate 12, the second end is the lower end of the second plate 12, the first plate 11 is located at the first end, and the third plate 13 is located at the second end. Along the second direction L2 extending along the thickness of the second plate 12, the first plate 11 and the third plate 13 are

[0077] 13 is located on both sides of the second plate 12. Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig.10 , Fig.14 , Fig.15 , Fig.16 and Fig.18 The photovoltaic module includes: a frame 31 and a photovoltaic laminate 32. The frame 31 has a mounting groove for accommodating the photovoltaic laminate 32, and a cavity connected to the mounting groove.

[0078] In view of the above technical problems, in the utility model, reference is made to Figure 2 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.14 , Fig.15 , Fig.16 , Fig.17 and Fig.18 , in parallel with the first direction L1, the support blocking member 2 is located on the side of the second plate 12 away from the first plate 11, and the support blocking member 2 abuts against the pressing block body 1 and the photovoltaic module, thereby preventing the first plate 11 and the second plate 12 from twisting and turning outward, and preventing the first plate 11 and the second plate 12 from driving the entire pressing block body 1 to twist and turn outward, such as Figure 2 In the embodiment, the support stopper 2 is used to protect the frame 31, prevent the frame 31 from deforming and shifting, thereby preventing the first plate 11, the second plate 12, etc. from turning outward, and thus effectively preventing the second plate 12 from being damaged. Since the first plate 11 and the second plate 12 can be prevented from twisting and turning outward, the deformation and displacement of the photovoltaic laminate are reduced, which greatly reduces the risk of the photovoltaic module falling off the photovoltaic bracket.

[0079] It should be noted that the photovoltaic laminate 32 may include: a solar cell, a front encapsulation film and a cover plate located on the light-facing side of the solar cell, and a rear encapsulation film and a back plate located on the backlight side of the solar cell.

After the photovoltaic module is assembled, the frame 31 is placed on the fourth plate 21. The fourth plate 21 has a clamping and fixing effect on the frame 31 or the photovoltaic module, and has a limiting effect on the pressing block body 1, which can prevent the first plate 11, the second plate 12, etc. from turning outward, and prevent the frame 31 from turning outward, thereby effectively avoiding damage to the pressing block body 1 and the frame 31, so that the deformation and displacement of the photovoltaic laminate are reduced, which greatly reduces the risk of the photovoltaic module falling off the photovoltaic bracket.

After the photovoltaic module is assembled, the frame 31 is placed on the fourth plate 21, and the fourth plate 21 has a limiting effect on the frame 31 or the photovoltaic module, and has a limiting effect on the pressing block body, which can prevent the pressing block body and the frame from turning outward. As shown in the figure, the first plate 11, the second plate 12, etc. can be prevented from turning clockwise, etc., and then the pressing block body can be effectively prevented from being damaged, so that the deformation and displacement of the photovoltaic laminate are reduced, which greatly reduces the risk of the photovoltaic module falling off the photovoltaic bracket. At the same time, the eighth plate 15 abuts against the fourth plate 21, which is also easier to assemble the frame 31 or the photovoltaic module.

[0093] Optional, see Fig. 9 , Fig.10 , Fig.11 and Fig.12 , along the direction parallel to the aforementioned second direction L2, the eighth plate 15 and the fourth plate 21 abut against each other, and abutting in this direction, the assembly of the pressing block body 1, the supporting blocking member 2 and the photovoltaic module is simple. The contact surface of the eighth plate 15 and the fourth plate 21 is provided with a concave-convex matching structure, which can not only play a positioning role, but also the concave-convex matching structures here abut against each other, which can also improve the reliability of the matching between the two, for example, Figures 9 to 12 In the figure, the semicircular opening on the eighth plate 15 and the semicircular opening on the fourth plate 21 are the concave-convex matching structure here. The semicircular opening on the eighth plate 15 and the semicircular opening on the fourth plate 21 together constitute the second through hole 211.

[0094] Optional, see Fig.13 , Fig.14 , Fig.15 and Fig.16 Along the direction parallel to the first direction L1, the pressing block body 1 abuts against the fourth plate 21, and the eighth plate 15 is placed on the fourth plate

[0095] On the fourth plate 21, it can be considered that the eighth plate 15 abuts against the fourth plate 21, and abuts in this direction, and the assembly of the pressing block body 1, the supporting blocking member 2 and the photovoltaic module is simple. The frame 31 is placed on the fourth plate 21, and the fourth plate 21 limits the pressing block body. The fourth plate, the fifth plate, and the sixth plate limit the frame, which can prevent the pressing block body and the frame from turning outward. As shown in the figure, the first plate 11, the second plate 12, etc. can be prevented from turning clockwise, etc., and thus the pressing block body can be effectively prevented from being damaged, so that the deformation and displacement of the photovoltaic laminate are reduced, and the risk of the photovoltaic module falling off the photovoltaic bracket is greatly reduced. Moreover, the pressing block body 1 can be directly placed on the fourth plate 21, and there is no requirement for the pressing block body. It is applicable to all existing pressing blocks and has stronger versatility. Optionally, a concave-convex matching structure may also be provided on the contact surface between the eighth plate 15 and the fourth plate 21. The concave-convex matching structure can not only play a positioning role, but also the concave-convex matching structures here abut against each other, which can also improve the reliability of the matching between the two.

[0096] Optional, see Fig.16 , the supporting blocking member includes: the tenth plate member 25 and the eleventh plate member 26 connected to the fourth plate member 21 in sequence, and the fourth plate member 21, the tenth plate member 25 and the eleventh plate member 26 form a bottom edge snap-in groove of the pressing block body. The bottom edge snap-in groove of the pressing block body and the bottom edge snap-in groove of the frame are located on the same side of the fourth plate member 21. In parallel with the aforementioned second direction L2, the bottom edge snap-in groove of the frame and the bottom edge snap-in groove of the pressing block body are relatively distributed, and the opening directions are opposite. In parallel with the second direction L2, the eighth plate member 15 includes: a protrusion facing away from the second plate member 12. Along the first direction L1, the pressing block body 1 abuts against the fourth plate member 21, that is, the eighth plate member 15 abuts against the fourth plate member 21, and the protrusion of the eighth plate member 15 is snapped into the bottom edge snap-in groove of the pressing block body. Furthermore, in parallel to the aforementioned second direction L2, the relatively distributed bottom edge retaining grooves of the frame and the bottom edge retaining grooves of the pressing block body limit both sides of the assembled structure of the pressing block body 1 and the photovoltaic component, thereby reducing the displacement and deformation of the pressing block body 1 and the photovoltaic component.

[0097] Optional, see Fig.17 and Fig.18 , or, refer to Figures 2 to 6 The support and blocking member includes: a ninth plate member 24 extending along the aforementioned first direction L1. In the aforementioned first direction L1, the ninth plate member 24 abuts against the second plate member 12. On the one hand, the structure of the support and blocking member is simple. On the other hand, in parallel with the first direction L1, the ninth plate member 24 exerts a force on the second plate member 12 toward the first plate member 11, which can prevent the first plate member 11, the second plate member 12, the third plate member 13, etc. from twisting. As shown in the figure, the first plate member 11, the second plate member 12, etc. can be prevented from turning clockwise, etc., thereby effectively preventing the first plate member 11, the second plate member 12, etc. from turning clockwise, etc.

[0098] Avoiding damage to the main body of the pressing block reduces the deformation and displacement of the photovoltaic laminate, which greatly reduces the risk of the photovoltaic module falling off the photovoltaic bracket. Moreover, the main body 1 of the pressing block can directly abut against the ninth plate 24, without any requirements for the main body of the pressing block, and is applicable to all existing pressing blocks, with stronger versatility.

[0099] Optional, see Figure 2 , Figure 4 , Figure 6 , Fig.17 and Fig.18 The third plate 13 includes a limiting groove abutting against the ninth plate 24.

[0100] Optional, see Figure 2 , Figure 3 , Figure 5 , Figure 6 The support and blocking member 2 further includes: a ninth plate member 24 integrally connected to the fourth plate member 21, the ninth plate member 24 and the fifth plate member 22 have a portion that is distributed opposite to each other, and the ninth plate member 24 and the fifth plate member 22 are located on the same side of the fourth plate member 21. Figure 2 , Figure 6 In the aforementioned first direction L1, the ninth plate 24 abuts against the second plate 12 to support the pressing block body 1. The ninth plate 24 here can prevent the first plate 11, the second plate 12, the third plate 13, etc. from twisting. As shown in the figure, the first plate 11, the second plate 12, etc. can be prevented from flipping clockwise, etc., thereby effectively avoiding damage to the pressing block body, reducing the deformation and displacement of the photovoltaic laminate, and greatly reducing the risk of the photovoltaic module falling off the photovoltaic bracket.

[0101] against Figure 2 The photovoltaic pressing block shown in the figure, during the assembly process of the photovoltaic module and the pressing block, refer to Figure 5 , you can first buckle the support blocking member 2 and the photovoltaic module, and then refer to Figure 6 , place the pressing block body 1 on the photovoltaic assembly and the ninth plate 24, so that the ninth plate 24 and the second plate 12 are abutted and connected, and then use fasteners such as bolts to fix it on the photovoltaic bracket.

[0102] Optional, see Fig. 9 , Fig.10 , Fig.11 , Fig.12, along the direction parallel to the second direction L2, when the eighth plate 15 and the fourth plate 21 are in contact, a first through hole 131 is provided on the third plate 13, and a second through hole 211 is provided at the contact position between the eighth plate 15 and the fourth plate 21. The center line of the first through hole 131 is colinear with the center line of the second through hole 211, and the second through hole 211 reserves space for the setting of the fastener. Here, the aperture of the second through hole 211 is larger than the aperture of the first through hole 131, which is convenient for the insertion of the fastener. For example, the first through hole 131 is a circular hole, and the second through hole 211 is an oblong hole. In any direction, the aperture of the oblong hole is larger than the aperture of the first through hole 131. At the same time, a hole is opened at the contact position, and the hole can also be used as a positioning mark during the splicing process of the two. It should be noted that there is no specific limit on how much larger the aperture of the second through hole 211 is than the aperture of the first through hole 131.

[0103] Here, the first through hole 131 and the second through hole 211 can also refer to the above-mentioned related records.

[0105] Optional, see Fig. 9 , Fig.10 and Fig.11 A third fillet is provided at the internal intersection of the seventh plate 14 and the eighth plate 15 to avoid the third fracture caused by stress concentration at this position.

[0106] Optionally, the radius corresponding to the third fillet is 0.1 mm to 5 mm, and the size of the third fillet is more appropriate, and the effect of avoiding stress concentration is more obvious. For example, the radius corresponding to the third fillet can be 0.1 mm, or 0.9 mm, or 1.8 mm, or 2.4 mm, or 2.5 mm, or 3.4 mm, or 4.7 mm, or 5 mm.

[0107] Optional, see Fig. 9 , Fig.10 , Fig.11 , the surface of the eighth plate 15 facing away from the seventh plate 14 is a concave-convex surface. After the eighth plate 15 contacts the bracket system, the surface of the eighth plate 15 facing away from the seventh plate 14 is subjected to a larger friction force, which has a stronger limiting effect on the pressing block, and the pressing block is not easy to move. The concave-convex surface here can be a wavy shape, a step shape, or a surface formed by multiple spaced ribs extending along the length direction of the eighth plate 15. The length direction of the eighth plate 15 here can be perpendicular to the paper surface.

[0108] Optional, see Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 The sixth plate 23 is formed by bending from the end of the fifth plate 22.

The matching here may be shape matching, size matching, etc. Then, the surface of the first plate 1 close to the mounting groove is more closely fitted to the outer surface of the mounting groove. Therefore, when the photovoltaic module is under load, the limiting effect on the photovoltaic module is stronger, thereby avoiding deformation of the photovoltaic module to a large extent.

[0110] Optional, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.14 , Fig.15 , Fig.16 , Fig.17 and Fig.18 The surface of the first plate 1 close to the installation groove and the portion away from the second plate 12 is an arc surface. The shape of the surface of the first plate 1 close to the installation groove and the portion away from the second plate 12 is more similar to the shape of the surface of the existing installation groove close to the first plate 1.

[0111] In order to be close or match, it is more closely fitted with the surface of the existing installation groove close to the first plate 1, so when the photovoltaic module is subjected to load, the limiting effect on the photovoltaic module is stronger, thus avoiding the deformation of the photovoltaic module to a large extent.

[0112] Optional, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.14 , Figures 15 to 18 The surface of the first plate 11 close to the mounting groove and the part close to the second plate 12 are concave-convex surfaces, and the friction between the concave-convex surface and the surface in contact with the frame 31 is relatively large, so when the photovoltaic module is under load, the limiting effect on the photovoltaic module is stronger. The concave-convex surface here can be a wavy shape, a step shape, or a surface formed by a plurality of spaced ribs extending along the length direction of the first plate 11. The length direction of the first plate 11 here can be perpendicular to the paper surface.

[0113] Optional, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.14 , Figures 15 to 18 The seventh plate 14 and the second plate 12 are located on both sides of the third plate 13. The thickness of the second plate 12 is greater than the thickness of the seventh plate 14. Specifically, since the second plate 12 is easy to tear, the thickness of the second plate 12 is increased, the mechanical properties of the second plate 12 are enhanced, and the life of the pressing block can be improved.

[0114] Optionally, the thickness of the second plate 12 is 2 mm to 7 mm, and the thickness of the second plate 12 is suitable, which not only enhances the mechanical properties of the second plate 12, but also avoids material waste. For example, the thickness of the second plate 12 can be 4.3 mm to 7 mm. For another example, the thickness of the second plate 12 can be 2 mm, or 2.4 mm, or 3 mm, or 3.3 mm, or 4 mm, or 4.3 mm, or 4.81 mm, or 5 mm, or 5.33 mm, or 5.6 mm, or 6 mm, or 6.7 mm, or 7 mm.

[0115] Optional, see Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.14 and Fig.15 , along the direction away from the second plate 12, the thickness of the first plate 11 decreases. Specifically, the position closer to the second plate 12 is more likely to be damaged, while the position away from the second plate 12 is not easily damaged. Therefore, reducing the thickness of the position that is not easily damaged can not only reduce the cost, but also does not reduce the life of the block. For example, the position farthest from the second plate 12 in the first plate 11, which can be the leftmost position of the first plate 11 in the figure, has a thickness of 3mm, or greater than or equal to 2.5mm and less than or equal to 3.7mm, which can not only reduce the cost, but also does not reduce the life of the block.

And / or, at the junction of the second plate 12 and the third plate 13, a second chamfer or a second fillet is provided on the side away from the mounting groove, which can also reduce the fracture at this position caused by stress concentration and enhance the connection strength. The angle of the second chamfer can be 30°, 45°, 60°, etc., and there is no limitation on the specific angle of the second chamfer.

[0118] Optionally, the radius corresponding to the second fillet is greater than 0 and less than or equal to 3 mm, and the size of the second fillet is more appropriate, and the effect of avoiding stress concentration is more obvious. For example, the radius corresponding to the second fillet can be 0.1 mm, or 0.9 mm, or 1.5 mm, or 2.0 mm, or 2.3 mm, or 2.7 mm, or 3 mm.

The cavity includes: a protrusion 311 protruding from the cavity along the second direction L2 on the side away from the mounting groove, and the protrusion 311 is snapped into the bottom snap-in groove of the frame, which well limits the frame 31 and makes it difficult for the frame 31 to be displaced.

[0122] Optional, see Fig.14 , Fig.15 and Fig.16, along the aforementioned first direction L1, the block body 1 abuts against the fourth plate 21, or the eighth plate 15 abuts against the fourth plate 21 to support the block body 1, and the size of the surface of the fourth plate 21 close to the first plate 11 is larger than the size of the surface close to the fourth plate 21 after the photovoltaic module and the block body 1 are assembled, which is convenient for placement. The photovoltaic module or the frame 31 and the block body 1 will not be suspended in the air, and the fourth plate 21 has a good supporting effect on the frame 31 and the block body 1. The specific size difference between the two surfaces is not specifically limited.
